UNITED STATES PATENT OFFICE.

FREDERICK -YV. BOND, OF CYPRESS HILL, NEW YORK, ASSIGNOR TO JOHN B. MURRAY, OF NEW YORK, N. Y.

IMPROVEMENT IN TOURNIQUETS.

Specification forming part of Letters Patent No. 38,442, dated May 5, 1863.

T0 a/ZZ whom/ it may concern:

Be it known that I, FREDERICK W. BOND, of Cypress Hill` county of Kings, State of New York, have invented certain new and useful Improvements in Tourniquets; and l do hereby declare that the following is a full and correct description thereof, reference being had to the annexed drawings, and to the letters of reference thereon.

My invention consists in the employment of an endless elastic band of vulcanized rubber, Iliade endless in the process of manufacture, (it being a section cut from a tubular piece of rubber of proper size,) in the combination of pad and elastic ligature.

The drawings illustrate my invention, Figure l being a plan view, Fig. 2 side view, `and Fig. 3 an end view, of my improved tourniquet.

Letter c represents the endless elastic vulcanized-rubber ligature, b the pad, d an additional pad, if required, and o a loop made by securing both ends of astrap to the pad. Theloop may be made by cutting two parallel gashes in theleather covering of theback part of the pad, or in many ways obvious to a skillful mechanic. Now, it will be evident that the main result of my invention will be effected by the use of a ligature made elastic by combining elastic with non-elastic materials; but such a ligature will not be as effective, permanent, or cheap as the endless vulcanized-rubber ligature, which has also the advantage of not being affected by cold.

The object of my invention is to provide soldiers and surgeons with a convenient and edective tourniquet ready at all times for immediate use.

I claim- The employment of an endless band of vulcanizedrubber as an elastic ligature in the combination of pad and elastic ligature, substantially as described.
